CARDING-IVIACHINE.

To all whom t may concern:

Be it known that I, PETER HARDMAN, a citizen of the United States, residing at VVillimantic, county of Vindham, State of Connecticut, have invented certain new and useful Improvements in Carding-Machines, of which the following is a full, clear, and exact description.

This invention relates to carding machines and is essentially an improvement on the structure disclosed in my former Patent No. 993,677, dated May 30, 1911.

The object of the present invention is to provide means of special character for more minutely removing impurities from the material on the lickerin roll.

In the accompanying drawing the figure is a side elevation partly in section and dial stock 1s fed to the liclrerin 3 by which it is grammatic in character', illustrating my improved construction and arrangement of parts.

1 represents the surface of the main carding cylinder, said surface being provided with the usual card clothing.

2 2 represent the usual so-called Hats.

3 represents a liclerin roll arranged properly relatively to the surface of the cylinder 1 to perform that function characteristic of a liclerin roll.

4 represents a feed roll.

5 represents the lap roll. rThe stock is fed from the lap roll 5 past the feed roll 4 to the lickerin 3. The adjacent surfaces of the cylinder 1 and the lickerin 3 move in the same direction, as shown by the arrows, the former at a greater speed than the latter.

8 represents a stripping cylinder corresponding in arrangement and function tothe stripping cylinder described in my former patent. The surface of this stripping cylinder 8 is spaced away from the lickerin roll only a few thousandths of an inch.

11 is a doffer or stripping comb preferably associated with the surface of the stripping cylinder 8 so as to remove the waste therefrom. The comb 11 may oscillate, being operated in any suitable way, as by an eccentric 12 connected by a link 13 to the aforesaid comb. The stripping cylinder 8 is provided with suitable card clothing, and said cylinder is caused to revolve at a comparatively slow speed so that waste gathered on the surface will be transferred around to where it will be engaged, and removed, by the comb 11. 14 is a second stripping cylinder, having suitable card clothing Specification of Letters latent.

thereon, preferably arranged for finer work, said stripping cylinder being mounted in close proximity to the surface of the liclerin 3, and between the stripping cylinder 8 and the main cylinder 1, although free of the p latter. The means for removing the waste gathered on' the surface of the stripping cylinder 14 1s of special construction, being v adapted to the particularly line waste material accumulated by the second stripping cylinder 14, This waste removing means preferably comprises a suction nozzle leading to a suitable eXhauster 16. The surface speed of the stripping cylinder 14 is comparatively slow for the same reason that the surface speed of the stripping cylinder 8 is comparatively slow.

In operation the action is as follows: The

taken on the card surface thereof and carried rapidly in the direction of the arrows, past the stripping cylinders 8-14 respectively, and thence on to the main carding v cylinder 1. heavier impurities tend to seek the surface of the stock and they are hence first caught 1 by the surface of the stripping cylinder S at It has been found that the a point somewhat in advance of the point ;where the combing action takes place between the stripping cylinder 8 and the lickerin. i cylinder moves in the same direction as the Since the surface of the stripping surface of the lickerin, it follows that even i though the heavier impurities are thrown l off, they may carry with them valuable fiber,

which will be reclaimed during the combing action which is thus bound to occur by reason of the direction of rotation of said cylinder. Any impurities which escape the stripping cylinder 8 proceed on to the second stripping cylinder 14, the card clothing of which is preferably adapted to operate on partially cleaned stock, and here, namely, on the line where the surface of the second stripping cylinder 14 is closest to the liclrerin 3, a second cleansing and combing action takes place, so that the more elusive -impnrities are effectively removed before lar. type of clearing mechanism used,Y

namely, the exhauster, and also because, the heavier waste vproducts being absent when the stock reaches the second cylinder, no

substantial part of the waste is delivered to l l dependent stripping cylinders arranged adthe surface of the second stripping cylinder until it reaches the point where the combing j action takes place.,

It is important that the surface of the two stripping cylinders 8-14 be separated substantially from each other and also from the surface of the main carding cylinder 1, since any interference between said surfaces would destroy the effectiveness of operation of the apparatus claimed.

In the event special means, such as shown in my accompanying application, Serial No.

f 652,490, is provided, it may be possible to rotate the stripping cylinder 8 in a reverse direction to that shown Iin the drawing. From a broad standpoint, therefore, the invention is not dependent upon the particular direction of rotation of the cylinder 8, although it is preferred that said stripping cylinder 8 should revolve in a direction to causegits surface to move in the same direction as the surface of the lickerin. It is ob vious that a doifer, similar to that shown in connection with the stripping cylinder 14, may be employed in some cases with the stripping cylinder 8 instead of the comb Shown. A further advantage of providing two independent stripping cylinders 8-14 is found in the fact that in some grades of Work advantages can be gained by varying the relative speeds of said stripping cylinders compared with each other and with the y speed of the lickerin.

While I have not shownI apparatus for driving the several cylinders, it should be understood that any suitable driving apparatus may be employed by which said parts may be given the desired speed and direction of rotation.

Vhat I claim is: f f

1. In a cardingfmachine, a main carding cylinder, a lickerin roll adjacent thereto, the adjacent surfaces of said cylinder and said rollv moving in the same direction, the former at a greater speed, a plurality of independent stripping cylinders arranged adjacent to said lickerin roll andV separated VCopies: of this patent may be obtained for ve cents each, by addressing the. Commissioner of Patents, l

jaeent to said liclrerin roll and separated from each other and from the main cylinder, the surfaces of said stripping cylinders p moving at a very much slower rate of speed than the speed of travel of the surface of t-he lickerin roll, and means for removing impurities gathered on the surface of each of said stripping cylinders.

3. In a carding machine, a main carding cylinder, a lickerin roll adjacent thereto, the adjacent Surfaces of said cylinder and said roll moving in the same direction, the former at a greater speed, a plurality of independent stripping cylinders arranged ad# jacent to said liclrerin roll and separated from each other and from the main cylinder, the surfaces of said stripping cylinders moving at a very much slower rate of speed than the speed of travel of the surface of the liclrerin roll, and means for removing impurities gathered on the surface of each of said stripping cylinders, one'of said means com risinoV a suction nozzle arranged closel r i adjacent thereto.

4:. In a carding machine, a main carding cylinder, a lickerin roll adjacent thereto, the
